BACKGROUND OF THE INVENTION

1. Field of the Invention The invention relates to a sealing plug of atoilet tank and, more particularly, to a sealing plug structure oftoilet tank for users to watch and to adjust the amount of drainingwater, to thereby conveniently operate the adjustment of the amount ofdraining water.

2. Brief Description of the Related Art

As shown in FIG. 1, it is a conventional toilet tank lever structure,FIG. 1 is a cross-sectional schematic diagram of a conventional drain 1,its sealing plug 1 includes a cover 11, a plunger 14 and an adjustablelever 15, and is matched with a sealing pad 12 and a gasket 13, whereina water inlet hole 141 is set on the bottom 140 of the plunger 14, andan air hole 142 is set on its lateral edge. One end of the adjustablelever 15 is fastened on the cover 11, a baffle 151 is set on its anotherend, the baffle 151 is against on the bottom 140 of the plunger 14, athrough hole 152 is set on the baffle 151, the through hole 152 iscorresponded to the water inlet hole 141 of the plunger 14. When a userwant to adjust the amount of draining water of the toilet tank, the usermay directly twist the plunger 14 by hands, and the relative position ofthe water inlet hole 141 of the plunger 14 with respect to the throughhole 152 on the baffle 151 of the adjustable lever 15 is changed, apartial or the whole area of the water inlet hole 141 of the plunger 14is blocked by the baffle 151, to thereby adjust the watering speed ofthe water inlet hole 141 of the plunger 14, the water inlet hole 141 maybe adjusted from fully open to fully closed, so that the closing time ofthe sealing plug 1 may be fine tuned, to control the amount of drainingwater. The above structure is the structure claimed by the patentUS2010/0212080 A1.
